Calico M950

The Calico M950 was a weapon that was set to appear in Resident Evil 2 but was not featured in the final version of the game. However, certain pieces of information, such as its inventory icons, do exist, allowing some modders to re-add the weapon to the game

It can be accessed in the Gamecube version by hacking the Colt S.A.A. into Leon's inventory.
